Jeep 2000 GCL, turn signals work intermittently, hazards work fine

[mgtyjoe]

Hi everyone. I am having a very annoying problem with my 2000 Jeep Grand Cherokee Laredo. Every once in a while, the turn signals wont flash at all. When you turn the lever left or right, the display won't even show the blinking flashers and you don't hear the 'clicking' that they are working. I have actually gotten out of the vehicle and looked and they are not working. As the day progresses, they usually start working about mid-day.

If you turn on the hazards, they always work just fine.

I have noticed it most if I park outside and wonder if moisture might be the problem.

I had my mechanic replace the multi-function switch last year, but it didn't really help. He asked me (because he could not remember this morning) if the wiring harness is internal or external. He was thinking about replacing the wiring to see if that worked.

The dealer wont' even look at it unless the signal lights stop working completely. Both local dealers told me if I bring it in and it works, they can't diagnose the problem. My mechanic is willing to keep chasing the problem until it goes away.

Does anybody out there have any insight on this? My thoughts are that condensation is getting in a faulty wire and as the day progresses, this evaporates and allows it to work again. I also wondered if perhaps the turn signal lever could be replaced and if that might help.

so far, after doing some research on this problem, i have found suggestion to:

1.) change clock spring, or

2.) change signal lever

My mechanic replaced the multifunction switch about 6 months ago to no avail. when he gets back, i think i'll try the clockspring.
